WORK CLAMP OR GUARD FORTYPE-WRITING MACHINES.

SPECIFICATION forming part of Letters Patent No. 747,958, dated December29, 1903.

Application filed February 7, 1901- Serial No. 46,362. (No model.)

To all whom it may concern:

Be it known that LROBERT JOSEPH FISHER, a citizen of the United States,residing at Athens, in the county of McMinn and State of Tennessee, haveinvented a new and useful Work Clamp or Guard for Type-Writing Machines,ofwhich the following is a specification.

This invention relates to type-writing machines, and has specialreference to means for protecting or holding or for assisting in holdinga card, sheet, page, or other work in the printing position.

To this end the invention primarily contemplates a work clamp or guardfor typewriting machines adapted to cover or engage with the edge orother portion of the Work to serve as a protector therefor during theprinting operation, as well as a holder or auxiliaryholder designed tohold or to assist in holding the work in proper position to be printedupon by the type-writing machine.

' mechanism working thereover.

A further object ofthe invention is to provide a work guard or clamp ofthe character specified possessing special utility with book and loosesheetwork in. connection with book type-writing machines of that typeembodying a fiat platen anda traveling printing When employed inconnection with machines of this character, the device contemplated bythe present invention may serve to clamp or grip the top edge of thesheet or other piece of work to prevei'itslipping or shifting thereof,besides serving to protect the edge of the work from contact with thetraveling frame of themaohine or any of the mechanism carried thereby.

Another object of the invention is to provide means automaticallycontrolled by the movement of the machine for clamping the bill, sheet,or other work and preventing any shifting thereof during the travel ofthe machine thereover, as well as'to protect the top edge of the same,the said means being disposed for actuation by the machine to releasethe work when said machine has been shifted from its position directlyover the work at the completion of the writing.

A still furthcrobject of the inventionis to provide work-clamping meansconstructed in a manner to permit both longitudinal and lateraladjustment or extension thereof for the purpose of accommodating itsdimensions and position to the character .of the bill, sheet, card, orleaf which is designed to be clamped in position and protected againstaccidental displacement.

Many other objects and advantages will more readily appear as the natureof the invention is better understood during the course of the followingdescription of the novel construction,combination,and arrangement ofparts illustrated in the drawings and embraced within the scope of theappended claims.

The several instrumentalities comprising the invention and thefundamental features of the latter are necessarily susceptible to a widerange of modification without departing from the sphere or scope of theinvention. in its generic aspect. The preferred embodiment of theinvention, however, is shown in the accompanying drawings, in which-Figure 1 is a plan view of abilling-platen equipped with the work clamp,guard, or grip-plate contemplated by the present invention, thetype-writing machine being removed fromthe platen. tional view of theplaten and aportion of the machine, showing those parts which constitutean embodiment of this invention inthe positions illustrated in Fig. 1.Fig. 3 is abottom plan view of one embodiment of the guard or grip-plateand its immediately-connected parts. Fig. 4. is asectional'view, on asomewhat-enlarged scale, of a portion of the platen, illustrating moreclearly the relation of the grip-plate, its operating member,

Fig. 10 is a plan View of abilling-platen equipped with that form of grip-plate or workclampillustrated in Figs. 6 to 9, inclusive, of the drawings; and Fig. 11 isa plan View of a platen equipped with that form of gripplate orwork-clamp illustrated in Figs. 1 to 5, inclusive, of the drawings, saidplate or clamp being associated with work-alining means secured directlyupon the platen.

Like numerals of reference designate corresponding parts in the severalfigures of the drawings.

The present invention contemplates the idea of utilizing, in connectionwith a typewriting machine, a work guard or clamp arranged to protect,as well as to hold or assist in holding, the sheet or other work inposition to receive the imprinted characters. This idea may be embodiedin a variety of structu res and utilized in connection with differenttypes of machines, although the same possesses special utility inconnection with the flat platen of a book type-writing machine of thetype disclosed in the patent to R. J. Fisher, No. 573,868. Hence forillustrative purposes the several embodiments of the invention are shownin the drawings in connection with the fiat platen and the guide-railsof a book type-writing machine, said platen and guiderails beingdesignated, respectively, by the numerals 1 and 2. This type of machinesinvolves printing mechanism supported for travel over the flat platen bya traveling frame 3, supporting the carriage of the printing mechanismand working upon the main tracks 2, which are toothed for engagementwith the pinions of the line-spacing mechanism. These features enterinto the general organization of the Fisher type-writing machine, whichis largely intended for writing in books, on letter-sheets, and formaking up records and'reports; but inasmuch as the same provides forprinting upon a sheet in a flat or spread-out condition it isnecessarily well adapted for printing upon folded or double bills, suchas are used in commercial billing. For the purpose of illustrating theapplication of my present invention, therefore, it is shown inconnection with a Fisher typewriting machine equipped with abillingplaten of the type illustrated and described in the concurrentapplication of Charles F. Laganke and Ralph D. Stackpole, Serial No.52,213. Such type of platens involves the employment of a work-holder orwork-holding frame consisting of a pair of oppositelylocated framemembers 4 and 5, constructed so as to not only hold a bill of the doubleor folded type, but also to hold the carbon sheet or element which isinterposed between the leaves of the bill. This work-holderis adapted tooccupya position beneath the printing mechanism and may be associatedwith the track-rails, which in this event are of the swinging type, soas to be movable in a direction toward or from the writing-surface ofthe platen.

In the type of machine here shown the continuous carbon element 6 iscarried by the oppositely-located winding-spools 7 and 8, arranged,respectively, heyond the rear and front edges of the work-holdingmembers 4 and 5, the rear winding-spool 7, which contains the roll ofcarbon-paper, being housed within a spool-pocket 9, formed in the platencontiguous to the rear ends of the members 4 and 5 and of a sufficientdepth to accom modate therein the spool 7 and the roll of carbonthereon.

The platen 1 of the machine is usually constructed of a metal body 10,having applied to the upper side thereof the usual writingsurface11,flat and unobstructed throughout, to provide for the even support ofthe work placed thereon, and, to facilitate handling of the work, thesaid platcn'maybe seated in the upper side of a suitable base or bed 12.

The several instrumentalities thus far described are constructed andarranged as in the Fisher type-writing machine now on the market or asdescribed and claimed in the application of Laganke and Stackpolehereinbefore referred to, and while these instrumentalities orstructural features constitute no part of my present invention they willserve the purpose of illustrating one application thereof and will lendperspicuity to the succeeding description of the said invention and tothe exposition of its several functions and advantages.

In a broad aspect the invention has for its object to provide, inconnection with workholding means-such, for instance, as has beendeseribeda workguard or a workclamp cooperating with such work holdingor positioning means to retain the work securely in the printingposition. In a more restricted aspect the invention has for its objectto provide a work clamp or guard which will be automatically moved toits operatingor clamping position to hold the work when the printingmechanism is moved to a position directly over said work and which willbe automatically moved to its releasing or inoperative position topermit the removal of the work from the platen when the printingmechanism is shifted away from the work at the completion of theprinting operation. In adapting the inventionto a flat-platentypewriting machine for the purpose of accomplishing these objects thereis employed a work-eugaging member located in a plane intermediate ofthe platen and printing mechanism and movable toward and from the platento engage or release the work disposed in the printing position. Thiswork-engaging member or clamp is preferably in the form of a swinginggrip-plate 13, which is arranged to swing over the spool-pocket 9 andclamp at its free edge upon the top edge of the folded bill or sheetwhich is held within the right-hand holding-frame 4. The swinging plate13 is provided upon its under side adjacent to its rear edge with aplurality of hinge-lugs 14,

IIO

receiving a hinge-rod 15, supported at the rear edge of the spool-pocket9, and thereby.

horizontal arms of which are bolted or otherwise secured to the underside of the platen in rear of the spool-pocket 9. The swingingwork-clamping plate 13 is preferably provided with a gripping edge 17,which engages with the top edge of the folded bill or sheet withsufficient firmness to hold the same against slipping and also preventsthe machine when thereof is provided with a flattened head 19,

loosely mounted on the hinge-rod 15 and bearing against the under sideof the plate 13. The rear end of said lever is formed into an inclinedupwardly-curved cam-arm 20, projecting upwardly through the platen to apoint above the writing-surface thereof and lying in the path of themachine-frame 3 between the tracks 2 and adjacent to the rear end of theplaten, the frame 3 constitutinga machine part movable independently ofthe tracks or guides to operate the clamp. When the machine is pushedback upon the rear ends of the tracks 2, the traveling frame 3 thereofengages with the inclined upwardlycurved cam-arm 20, thereby depressingthis arm and causing the flattened head 19 of. the operating-lever 18 tocarry the plate 13 to an elevated or Work-releasing position in front ofthe machine, as indicated in dotted lines in Fig. 4 of the drawings. Theplate 13 is thus caused to automatically release its hold from the topedge ofthe bill or sheet, whereby the same may be readily removed andanother bill or sheet put in the place thereof. By reason of theindependent connection of the head 19 of the operating-lever 18 with thehinge-rod 15 the plate 13 may be swung manually toa more nearly verticalposition when it is desired to removed the rear spool 7, carrying theroll of carbon-paper.

The invention has been described in connection with an approved type ofbillingplaten for the reason that it is possessed of special utility inconnection with commercial billing upon book type-writing machines; butit should be understood that the character of tal contact-roller 22.

work holding means cooperating with the clamping-plate described is notessential to the effective utilization of the invention, nor, in fact,is it necessary that any cooperating work-holding means he provided, asit is evident that in many co nnections-'as, for instance, in printingupon index-cards-the clamping element would be entirely sufficient forthe purpose of retainiugthe work in its printing position without theaid of other work-holding means. In another aspect of the invention itwill be seen to include, broadly, the idea of associating with a flatplaten a plurality of work-holding devices cooperating therewith anddisposed longitudinally and transversely thereof. It has also beensuggested that the work-holders, aside from their functions as retainingmeans for the work element, constitute protectors or guards for the edgeor edges of the sheet to prevent the machine from contacting with thelatter. In a still further aspect, therefore, the invention will be seento comprehend the idea of. providing a flat platen with a plurality ofwork guards or protectors distinctfrom the tracks or guides and disposedlongitudinally and transversely of the platen. Furthermore, since theclamp 13 also constitutes a guard. the inventionwill be seen tocomprehend a swinging machine-operated work-guard as distinguished froma machine-operated workclamp, it being obvious that while in theillustrated embodiment of the invention the guard serves in addition asa clamp it need not perform any function other than the protection ofthe work element. In Fig. 11 of the drawings-I have exemplified such anadaptation of the structure, as the clamping element or plateillustrated in this figure is shown upon a platen equipped simply withan angular work-alining guide 21, carried directly by. the platen andserving merely to properly aline the work and to retain itin its flat orspreadout condition over the writing-surface.

After a folded bill, sheet, or other piece of work is placed in theprinting position above the platen, whether with or Without the aid ofwork holding or alining means, the drawing forward of the machinepermits the work-' clamping plate 13, as well as the smoothing out ofthe bill or sheet, the traveling machineframe is preferably equippedwith a horizon- The said contact-roller 22 is journaled at itsextremities in suitable bearings 23*, applied to the lower portion of.

the machine-frame 1, as illustrated in Fig. 2 of the drawings.

For the purpose of exemplifying the scope of the invention, as well asto disclose a further development thereof,'I have illustrated in Figs. 6to 10, inclusive, of the drawings a structural variation of which theclampingplate is capable without departing from the considerableseparation of its sections.

principle or sacrificing any of the advantages of the invention. Thisvariation consists in making the clamping-plate extensible, and whileprovision might be made for effecting this extensibility in a lateral orlongitudinal direction only the illustrated structure makes it possibleto extend the plate both laterally and longitudinally to any desiredextent for the purpose of accommodating its dimensions to the dimensionsand character of the work to be clamped. The adjustment or extension ofthe clamping means might be effected in a large variety of ways whichwould naturally suggest themselves to a skilled mechanic; but said plateis preferably formed in a plurality of sections 23 and 24:, arrangedside by side, as shown, and mounted upon the hinge-rod 15 in a manner topermit said sections of the clamping-plate to be moved laterally andsecured at any desired point upon the rod for the purposeof adjustingthe plate transversely to accommodate the varying conditions of use.This character of mounting is secured by providing each of theplate-sections with a pair of hinge-lugs 14c, pierced by the rod 15 andopposed to the opposite ends of the adjusting sleeve or collar 25,designed to be shifted longitudinally upon the hinge-rod 15 and to besecured in its adjusted position by a set-screw 26 or other suitablesecuring means. In order to regulate the width of the clamping-plate, itis simply necessary to release the adjusting members or collars 25,which may then be shifted to any desired position and resecured toretain the platesections in their laterally-adjusted positions withoutinterfering with their swinging movement upon the hinge-rod 15. It isevident that the head 19 of the operating-lever 18 (illustrated in thefirst five figures of the drawings) would be inadequate to effect theoperation of the sectional clamping-plate in such adjustments of saidplate as would effect a To accommodate this lateral adjustment,therefore,.the front end of the fiat head 19 of the operating-lever 18,employed in connection with the sectional clamping-plate, is formed witha more or less extended crossbar 27 of sufficient length to insure theretention of the operating lever in operative relation with the sectionsof the clamping-plate, irrespective of the lateral adjustment of saidsections. In addition to the provision for this adjustment of thegrip-plate laterally or transversely of the platen the employment ofmeans for effecting its adjustment longitudinally thereof is alsocontemplated; but said means may be employed either with or with outthose instrumentalities which contribute to the lateral adjustment, asmay be desired inindividual instances. One embodiment of means foraccomplishing such longitudinal adjustment or extension of thegrip-plate is illustrated in Figs. 6 to 10, inclusive, of the drawings,and consists in forming each of the grip-plate sections 23 and 24 withaplurality of relatively adjustable members. These members (designated bythe numerals 28 and 29) may be and preferably are a pair of thin metalplates in lapping relation and retained in their relatively adjustedpositions by suitable retaining means,which permits the plates ormembers of the grip-plate sections to be adjusted to any desiredrelative positions and retained securely against accidentaldisplacement. One embodiment of such retaining means comprehends theformation of a longitudinal slot 30 in each of the under or lower platesor members to accommodate the play of depending elementsas, forinstance, retaining-screws 31, screwed into the under sides of theuppermost plates 28. The overlapping members or plates of the grip-platesections are preferably of rabbeted formation, as shown more clearly inFig. 7 of the drawings, in order to provide comparatively heavy portionsof the plates at those points where the pivotal mounting is efiected andwhere the work is gripped.

From the foregoing it will be apparent that the several forms of theinvention whi ch have been illustrated and described all embrace notonly a work clamp which retains the work and protects it from contactwith any portion of the traveling frame or mechanism carried therebyduring the shifting of the frame to its various positions over theplaten, but that these several forms of the invention also embody thethought of a work-clamp movable toward and from the platen to engage orrelease the work and disposed for control and automatic actuation by thetraveling frame or some element movable therewith, so that the work issecurely gripped and held while the printing mechanismis disposedthereover, but is automatically released to facilitate the displacementand replacement of the work when the printing mechanism has been shiftedto its position away from the work and at the rear end of the platen.

Various modifications other than those illustrated or suggested willnaturally occur to those skilled in the art, and, as many forms of gripmembers and actuating mechanism therefor may be resorted to in carryingout the invention, it will be understood that various changes in theform, proportion, and structural details of the present embodiments ofthe device may be resorted to without departing from the principle orsacrificing any of the advantages of this invention.
